Answer: C) 38000 Explanation: Here from the given information, The ratio of investments of Rajeev, Deepu & Shakti is R : D : S = (10000 × 12) : (12000 × 10) : (7200 × 8) = 25 : 25 : 12 Now the Profit = 2 × (72000-10000) = 124000 Share of Rajeev = 124000 x 25/62 = 48000 Profit of Rajeev = 48000 - 10000 = 38000

प्र: The difference between circumference and semidiameter of a circle is 37 cm. What is the diameter of the circle ? 1547 0

उत्तर : 4. "14 cm"
व्याख्या :
Answer: D) 14 cm Explanation: circumference of a circle = 2πr => 2 × 22/7 × r – r = 37 => 37/7 × r = 37 => r = 7 cm. Diameter D = 2r = 7×2 = 14 cm.

प्र: The length, breadth and height of a room are in the ratio 7:3:1. If the breadth and height are doubled while the length is halved, then by what percent the total area of the 4 walls of the room will be increased ? 1627 0

उत्तर : 1. "90%"
व्याख्या :
Answer: A) 90% Explanation: Let length, breadth and height of the room be 7, 3, 1 unit respectively. Area of walls = 2(l+b)xh = 2(7+3)x1 = 20 sq. unit. Now, length, breadth and height of room will become 3.5, 6 and 2 respectively. Area of walls = 2(l+b)xh = 2(3.5+6)x2 = 38 sq. unit. % Increase in the area of walls = (38-20)x100/20 = 90%.

प्र: Nine different letters of alphabet are given, words with 5 letters are formed from these given letters. Then, how many such words can be formed which have at least one letter repeated ? 1571 0

उत्तर : 1. "43929"
व्याख्या :
Answer: A) 43929 Explanation: Number of words with 5 letters from given 9 alphabets formed = 95 Number of words with 5 letters from given 9 alphabets formed such that no letter is repeated is = 9P5 Number of words can be formed which have at least one letter repeated = 95 - 9P5 = 59049 - 15120 = 43929
